<div>Hi Matt,</div>
<div> </div>
<div>I have seen CFN (confusion) messages when CICs are misconfigured and out of alignment. Eventually one switch gives up (by sending CFN) after sending many resets that are ignored by the second switch.<br> </div>
<div>It could be worth checking the CIC datafill at both ends of this SS7 link.</div>

It's used when you send a parameter to the other end that it doesn't recognize. I'm traveling right now, but I'll be back in about 2 days. I think then I can look more into this.
